In their own words
Universal File Opener
Universal File Opener is an offline viewer and editor for supported files on Android and Windows. Its tools cover PDFs, Office documents, spreadsheets, presentations, images, archives, text, code, data, audio, and video, with available capabilities varying by platform and format. The listing includes 214 formats, archive, Office, and code previews, and in-file search. Reading supported files is free without a file-count limit, expiry, or watermark, though individual formats have size and compatibility limits. Files are processed on the device: Android does not request INTERNET permission, and the Windows app makes no network connections of its own. The apps have no advertising, app analytics, or Krauq account requirement. Android can read English text from scans using offline OCR. Files can be opened through Android sharing or file-picker features, or Windows dialogs and drag and drop; cloud providers handle their own downloads and syncing. Android Pro costs $1.99 a month or $9.99 a year. The listed lifetime option costs $5,029.99, paid once.
